any truth to this story? any proof or something? law 2alo monkeys kenna 2elna, bas Dolphins? how?

all life on earth came from water originally. we still have many things in common with fish one of the famous examples is the laryngeal nerve.

this nerve is supposed to connect the brain to the neck... logicly speaking it should be a small nerve about 20 to 30 cm long(the distance from the brain to the neck is not that far) instead this nerve goes down from the brain to the heart(in humans and all animals) wraps around it, and then goes back up to the neck, in a useless dangerous way. what the scientists discovered is that in fish, the nerve does the same thing, except in fish, this is the only direct way it can take to reach the neck, when evolution progressed from fish, it is impossible to go back and redo this(it's not like at some point you can cut the nerve and redraw its route), so the path of that nerve remained and grew bigeer, for giraffes, the route is 3 meters long instead of being 20 cm!

You probably know that back in the day, medical professionals used leeches to treat pretty much everything from fevers to leech allergies. This old Greek guy named Galen postulated that there were four humors in the body--blood, phlegm, black bile and yellow bile--and that an excess of one fluid over the others lead to the vast majority of ailments. If a patient presented with bloodshot eyes it wasn't from a late night grog bender, it was because they had too much blood and needed to be drained. All that extra blood can really mess a guy up.

As you can imagine, this was all about as scientific as anything taught in a Deep South biology classroom. But, thanks to the reverence future generations of doctors held Galen in, it remained a prominent medical treatment for centuries.

As doctors began to refine their craft with innovations like washing their hands and not spitting in open wounds, leech medicine fell out of favor. But sometimes we see that the crazy old-time bastards had it right.

Recent studies have shown that leech saliva is basically a damned miracle elixir. Their spit is lousy with anesthetic, antibiotics and beneficial enzymes and anticoagulants that could prevent heart attacks and strokes.

The problem is, of course, people aren't huge on the idea of their surgeon striding into the operating theater with a big-ole jar full of leeches and pond water. So the research now is about trying to get the leech benefits without the leeches, probably the most hilarious being the "mechanical leech." Yeah, that'll make people feel better.
